ABSTRACT
PURPOSE: Staphylococcus aureus prosthetic valve endocarditis (SAPVE) is a serious infection with high mortality. The main objective of this study was to identify factors associated with in-hospital mortality. METHODS: From January 2008 to December 2021, consecutive patients from a Spanish cohort of infective endocarditis with a definitive diagnosis of SAPVE were analyzed. RESULTS: During the study period, 219 cases of definitive SAPVE were diagnosed, which accounted for 16.7% of a total of 1309 cases of definitive prosthetic valve endocarditis (PVE). Patients presented advanced age and marked comorbidity. There was a higher incidence of persistent bacteremia, septic shock, stroke, and acute kidney injury than in cases of PVE caused by other microorganisms. Methicillin resistance was not associated with differences in clinical presentation, echocardiographic findings, or mortality. Only 50.6% of the patients with surgical indications (88 patients) underwent surgery. Overall, in-hospital mortality was 47.9%. The variables associated with in-hospital mortality were age (OR:1.03, 95% CI: 1.00-1.05; p = 0.016), heart failure (OR:2.86, 95% CI: 1.53-5.32; p = 0.001), acute kidney injury (OR:2.42, 95%CI:1.28-4.58; p = 0.006), stroke (OR:3.53, 95%CI:1.79-6.96; p < 0.001) and surgery indicated but not performed (OR:2.01, 95%CI:1.06-3.8; p = 0.030). On the other hand, the performance of surgery per se in patients with SAPVE, regardless of whether there was a surgical indication according to the guidelines, was not associated with a reduction in in-hospital mortality. CONCLUSIONS: SAPVE is characterized by high mortality, which is more marked in patients who present a surgical indication but do not undergo surgery.
ABSTRACT
Background: Recurrent acute cholangitis (RAC) is a relatively uncommon entity that presents significant management difficulties. We present the case of a patient with RAC in whom the number of episodes was reduced after a novel therapeutic procedure. Case report: A 93-year-old male who in June 2019 was admitted for chills without fever, shivering, epigastric abdominal pain and moderate jaundice. Both abdominal ultrasound and CT scan showed intrahepatic and extrahepatic duct dilatation up to the papilla with no evidence of mass at that level. Endoscopic retrograde cholangiopancreatography (ERCP) was performed and abundant biliary sludge was removed. E. coli was identified as the cause of several of the episodes. Some isolates were shown to produce extended spectrum beta-lactamase (ESBL). Papillotomy was performed and plastic prosthesis and later a metallic prosthesis were implanted. Several months later a surgical bypass of the biliary tract was performed due to persistent episodes of cholangitis. When the chronic suppressive antibiotic treatment subsequently instituted to prevent new episodes of cholangitis failed, it was decided to perform a fecal microbiota transplant from a healthy donor and to suspend the chronic suppressive treatment. Since then, she has not presented new episodes of RAC for more than 10 months of clinical follow-up. BLEE-producing E. coli in the gastrointestinal tract could not be eradicated. Comment: Chronic colonization of the biliary tract by certain enterobacteria such as E. coli has been identified as a relevant pathogenic factor in cases of RAC. FMT may be a promising tool to improve the clinical course of patients with RAC.
ABSTRACT
BACKGROUND: The management and outcomes of nontuberculous mycobacterial (NTM) infections in solid organ transplant (SOT) recipients are poorly characterized. We aimed to describe the management and 1-y mortality of these patients. METHODS: Retrospective, multinational, 1:2 matched case-control study included SOT recipients aged 12 y old or older diagnosed with NTM infection between January 1, 2008, and December 31, 2018. Controls were matched on transplanted organs, NTM treatment center, and posttransplant survival at least equal to the time to NTM diagnosis. The primary aim was 1-y mortality after NTM diagnosis. Differences between cases and controls were compared using the log-rank test, and Cox regression models were used to identify factors associated with mortality at 12 mo among cases. RESULTS: In 85 patients and 169 controls, the median age at the time of SOT was 54 y (interquartile range, 40-62 y), 59% were men, and the lungs were the most common site of infection after SOT (57.6%). One-year mortality was significantly higher in cases than in controls (20% versus 3%; P < 0.001), and higher mortality was associated with lung transplantation (hazard ratio 3.27; 95% confidence interval [1.1-9.77]; P = 0.034). Median time (interquartile range) from diagnosis to treatment initiation (20 [4-42] versus 11 [3-21] d) or the reduction of net immunosuppression (36% versus 45%, hazard ratio 1.35 [95% CI, 0.41-4.43], P = 0.618) did not differ between survivors and those who died. CONCLUSIONS: NTM disease in SOT recipients is associated with a higher mortality risk, especially among lung transplant recipients. Time to NTM treatment and reduction in net immunosuppression were not associated with mortality.
ABSTRACT
BACKGROUND: Isavuconazole (ISA) and voriconazole (VORI) are recommended as the first-line treatment for invasive aspergillosis (IA). Despite theoretical advantages of ISA, both triazole agents have not been compared in solid organ transplant recipients. METHODS: We performed a post hoc analysis of 2 retrospective multicenter cohorts of solid organ transplant recipients with invasive fungal disease (the SOTIS [Solid Organ Transplantation and ISavuconazole] and DiasperSOT [DIagnosis of ASPERgillosis in Solid Organ Transplantation] studies). We selected adult patients with proven/probable IA that were treated for ≥48 h with ISA (nâ =â 57) or VORI (nâ =â 77) as first-line therapy, either in monotherapy or combination regimen. The primary outcome was the rate of clinical response at 12 wk from the initiation of therapy. Secondary outcomes comprised 12-wk all-cause and IA-attributable mortality and the rates of treatment-emergent adverse events and premature treatment discontinuation. RESULTS: Both groups were comparable in their demographics and major clinical and treatment-related variables. There were no differences in the rate of 12-wk clinical response between the ISA and VORI groups (59.6% versus 59.7%, respectively; odds ratio [OR], 0.99; 95% confidence interval [CI], 0.49-2.00). This result was confirmed after propensity score adjustment (OR, 0.81; 95% CI, 0.32-2.05) and matching (OR, 0.79; 95% CI, 0.31-2.04). All-cause and IA-attributable mortality were also similar. Patients in the ISA group were less likely to experience treatment-emergent adverse events (17.5% versus 37.7%; P = 0.011) and premature treatment discontinuation (8.8% versus 23.4%; P = 0.027). CONCLUSIONS: Front-line treatment with ISA for posttransplant IA led to similar clinical outcomes than VORI, with better tolerability and higher treatment completion.
ABSTRACT
Background: Several aspects of the occurrence and management of mycotic aneurysm (MA) in patients with infective endocarditis (IE) have not been studied. Objectives: To determine the incidence and factors associated with MA presence and rupture and to assess the evolution of those initially unruptured MA. Methods: Prospective multicenter cohort including all patients with definite IE between January 2008 and December 2020. Results: Of 4548 IE cases, 85 (1.9%) developed MA. Forty-six (54.1%) had intracranial MA and 39 (45.9%) extracranial MA. Rupture of MA occurred in 39 patients (45.9%). Patients with ruptured MA had higher 1-year mortality (hazard ratio, 2.33; 95% confidence interval, 1.49-3.67). Of the 55 patients with initially unruptured MA, 9 (16.4%) presented rupture after a median of 3 days (interquartile range, 1-7) after diagnosis, being more frequent in intracranial MA (32% vs 3.3%, P = .004). Of patients with initially unruptured MA, there was a trend toward better outcomes among those who received early specific intervention, including lower follow-up rupture (7.1% vs 25.0%, P = .170), higher rate of aneurysm resolution in control imaging (66.7% vs 31.3%, P = .087), lower MA-related mortality (7.1% vs 16.7%, P = .232), and lower MA-related sequalae (0% vs 27.8%, P = .045). Conclusions: MA occurred in 2% of the patients with IE. Half of the Mas occurred in an intracranial location. Their rupture is frequent and associated with poor prognosis. A significant proportion of initially unruptured aneurysms result from rupture during the first several days, being more common in intracranial aneurysms. Early specific treatment could potentially lead to better outcomes.
ABSTRACT
BACKGROUND: Few population-based studies have evaluated the epidemiology of infective endocarditis (IE). Changes in population demographics and guidelines on IE may have affected both the incidence and outcomes of IE. Therefore, the aim of our study is to provide contemporary population-based epidemiological data of IE in Spain. METHODS: Retrospective nationwide observational study using data from the Spanish National Health System Discharge Database. We included all patients hospitalized with IE from January 2000 to December 2019. RESULTS: A total of 64,550 IE episodes were included. The incidence of IE rose from 5.25 cases/100,000 person-year in 2000 to 7.21 in 2019, with a 2% annual percentage change (95% CI 1.3-2.6). IE incidence was higher among those aged 85 or older (43.5 cases/100.000 person-years). Trends across the study period varied with sex and age. Patients with IE were progressively older (63.9 years in 2000-2004 to 70.0 in 2015-2019, p < 0.001) and had more frequent comorbidities and predispositions, including, previous valvular prosthesis (12.1% vs 20.9%, p < 0.001). After adjustment, a progressive reduction in mortality was noted including in 2015-2019 compared to 2010-2014 (adjusted odds ratio 0.93, 95% confident interval 0.88-0.99, p = 0.023)., which was associated with more frequent cardiac surgery in recent years (15.1% in 2010-2014 vs 19.9% in 2015-2019). CONCLUSIONS: In Spain, the incidence of IE has increased during the XXI century, with a more pronounced increase in elderly individuals. Adjusted-mortality decreased over the years, which could be related to a higher percentage of surgery. Our results highlight the changing epidemiology of IE.

Mesenchymal stromal cells (MSC) have immunomodulatory and tissue-regenerative properties and have shown promising results in acute respiratory distress syndrome (ARDS) of multiple causes, including COVID-19. We conducted a randomised (1:1), placebo-controlled, double-blind clinical trial to assess the efficacy and safety of one bone marrow-derived MSC infusion in twenty patients with moderate to severe ARDS caused by COVID-19. The primary endpoint (increase in PaO2/FiO2 ratio from baseline to day 7, MSC 83.3 versus placebo 57.6) was not statistically significant, although a clinical improvement at day 7 in the WHO scale was observed in MSC patients (5, 50% vs 0, 0%, p = 0.033). Median time to discontinuation of supplemental oxygen was also shorter in the experimental arm (14 versus 23 days, p = 0.007), resulting in a shorter hospital stay (17.5 versus 28 days, p = 0.042). No significant differences were observed for other efficacy or safety secondary endpoints. No infusion or treatment-related serious adverse events occurred during the one-year follow-up. This study did not meet the primary endpoint of PaO2/FiO2 increase by day 7, although it suggests that MSC are safe in COVID-19 ARDS and may accelerate patients' clinical recovery and hospital discharge. Larger studies are warranted to elucidate their role in ARDS and other inflammatory lung disorders.Trial Registration: EudraCT Number: 2020-002193-27, registered on July 14th, 2020, https://www.clinicaltrialsregister.eu/ctr-search/trial/2020-002193-27/ES .

PURPOSE: To describe a cohort with a high risk of recurrence who received bezlotoxumab during the first episode of Clostridioides difficile infection (CDI) and to compare this cohort with patients with similar characteristics who did not receive the monoclonal antibody. METHODS: A prospective and multicentre study of patients with a high risk of recurrence (expected recurrence rate>35%) who were treated with bezlotoxumab during their first episode of CDI was conducted. A propensity score-matched model 1:2 was used to compare both cohorts that were weighed according to basal characteristics (hospital-acquisition, creatinine value, and fidaxomicin as a CDI treatment). RESULTS: Sixty patients (mean age:72 years) were prospectively treated with bezlotoxumab plus anti-Clostridioides antibiotic therapy. Vancomycin (48 patients) and fidaxomicin (12 patients) were prescribed for CDI treatment, and bezlotoxumab was administered at a mean of 4.2 (SD:2.1) days from the beginning of therapy. Recurrence occurred in nine out of 54 (16.7%) evaluable patients at 8 weeks. Forty bezlotoxumab-treated patients were matched with 69 non-bezlotoxumab-treated patients. Recurrence rates at 12 weeks were 15.0% (6/40) in bezlotoxumab-treated patients vs. 23.2% (16/69) in non-bezlotoxumab-treated patients (OR:0.58 [0.20-1.65]). No adverse effects were observed related to bezlotoxumab infusion. Only one of 9 patients with previous heart failure developed heart failure. CONCLUSION: We observed that patients treated with bezlotoxumab in a real-world setting during a first episode of CDI having high risk of recurrence, presented low rate of recurrence. However, a significant difference in recurrence could not be proved in comparison to the controls. We did not detect any other safety concerns.

INTRODUCTION: Antivirals and monoclonal antibodies lower the risk of progression in immunocompromised patients. However, combination therapy with both types of agents has not been studied. PATIENTS AND METHODS: This was a single-centre, prospective, cohort study. All immunocompromised patients who received treatment for mild-to-moderate COVID-19 from 1 January 2022 to 30 October 2022 were enrolled. The primary endpoint was COVID-19 progression at 90 days, defined as hospital admission or death due to COVID-19 and/or seronegative persistent COVID-19. RESULTS: A total of 304 patients were included: 43 patients (14.1%) received sotrovimab plus a direct-acting antiviral, and 261 (85.9%) received monotherapy. Primary outcome occurred more frequently after monotherapy (4.6% vs. 0%, P=0.154). Among patients with anti-spike immunoglobulin G (anti-S IgG) titre <750 BAU/mL, COVID-19 progression was more common after monotherapy (23.9% vs. 0%, P=0.001), including more frequent COVID-related admission (15.2% vs. 0%, P=0.014) and seronegative persistent COVID-19 (10.9% vs. 0%, P=0.044). Combination therapy was associated with lower risk of progression (odds ratio [OR] 0.08, 95% confidence interval [95% CI] 0.01-0.64). Anti-S IgG titre <750 BAU/mL and previous anti-CD20 were associated with higher risk of progression (OR 13.70, 95% CI 2.77-67.68; and OR 3.05, 95% CI 1.20-10.94, respectively). CONCLUSIONS: In immunocompromised patients, combination therapy with sotrovimab plus an antiviral may be more effective than monotherapy for SARS-CoV2.

BACKGROUND AND OBJECTIVES: The efficacy of COVID-19 convalescent plasma (CP) associates with high titres of antibodies. ConPlas-19 clinical trial showed that CP reduces the risk of progression to severe COVID-19 at 28 days. Here, we aim to study ConPlas-19 donors and characteristics that associate with high anti-SARS-CoV-2 antibody levels. MATERIALS AND METHODS: Four-hundred donors were enrolled in ConPlas-19. The presence and titres of anti-SARS-CoV-2 antibodies were evaluated by EUROIMMUN anti-SARS-CoV-2 S1 IgG ELISA. RESULTS: A majority of 80.3% of ConPlas-19 donor candidates had positive EUROIMMUN test results (ratio ≥1.1), and of these, 51.4% had high antibody titres (ratio ≥3.5). Antibody levels decline over time, but nevertheless, out of 37 donors tested for an intended second CP donation, over 90% were still EUROIMMUN positive, and nearly 75% of those with high titres maintained high titres in the second sample. Donors with a greater probability of developing high titres of anti-SARS-CoV-2 antibodies include those older than 40 years of age (RR 2.06; 95% CI 1.24-3.42), with more than 7 days of COVID-19 symptoms (RR 1.89; 95% CI 1.05-3.43) and collected within 4 months from infection (RR 2.61; 95% CI 1.16-5.90). Male donors had a trend towards higher titres compared with women (RR 1.67; 95% CI 0.91-3.06). CONCLUSION: SARS-CoV-2 CP candidate donors' age, duration of COVID-19 symptoms and time from infection to donation associate with the collection of CP with high antibody levels. Beyond COVID-19, these data are relevant to inform decisions to optimize the CP donor selection process in potential future outbreaks.

Coagulase-negative staphylococci (CoNS) are currently considered typical microorganisms causing infective endocarditis (IE) in patients with prosthetic valves. The objective was to determine variables associated with IE in patients with CoNS bacteremia. We performed an analysis of the clinical characteristics of patients with CoNS bacteremia admitted to a university hospital in Madrid (Spain) from 2021 to December 2022 according to the occurrence of IE. This study is an evaluation of a bacteremia registry. During the study period, 106 patients with CoNS bacteremia were detected. In 85 patients an echocardiogram was performed during hospital admission to rule out IE. Among them, 12 episodes were detected that met IE criteria (14.2%). Of the 6 patients with heart valve prostheses, 5 patients (83.3%) had IE (p < 0.001). Patients with IE more frequently had positive blood cultures more than 12 h after the first draw (58.3% versus 13.4%; p < 0.001). There was a tendency to associate community-acquired bacteremia and to that all blood culture bottles obtained were positive with an increased risk of IE (p = 0.091 and p = 0,057, respectively). Attributable mortality to infection was higher in patients with IE relative to all other patients (16.7% vs. 0%; p = 0.033). The multivariable analysis included having valve prosthesis and persistent bacteremia for more than 12 h. Both were independently associated with IE: valve prosthesis OR 38.6 (95% CI 5.8-258; p < 0.001) and persistent bacteremia OR 2.6 (95% CI 1.1-6.8; p = 0.046). In conclusion, a high percentage of cases of CoNS bacteremia may be due to IE. Some of the variables related to a higher risk of IE, such as having a valvular prosthesis or presenting positive blood cultures for more than 12 h, should lead to rule out or confirm the presence of IE by performing echocardiography.

BACKGROUND: Little is known about the incidence of influenza among admissions to the cardiac intensive care unit (C-ICU), accuracy of clinical suspicion, and influenza vaccination uptake. We evaluated the incidence of influenza at C-ICU admission during the influenza season, potential underdiagnosis, and vaccination uptake. METHODS: Prospective study at five C-ICUs during the 2017-2020 influenza seasons. A nasopharyngeal swab was collected at admission from patients who consented (n = 788). Testing was with Xpert®XpressFlu/RSV. RESULTS: Influenza was detected in 43 patients (5.5%) (40 FluA; 3 FluB) and clinically suspected in 27 (62.8%). Compared to patients without influenza, patients with influenza more frequently had heart failure (37.2% vs 22.8%, P = 0.031), previous contact with relatives with influenza-like illnesses (23.3% vs 12.5%, P = 0.042), antimicrobial use (67.4% vs 23.2%, P <0.01), and need for mechanical ventilation (25.6% vs 14.5%, P = 0.048). Patients received oseltamivir promptly. We found no differences in mortality (11.6% vs 5.2%, P = 0.076). Patients with influenza more frequently had myocarditis (9.3% vs 0.9%, P <0.01) and pericarditis (7.0% vs 0.8%, P = 0.01). Overall, 43.0% of patients (339/788) were vaccinated (51.9% of those with a clear indication [303/584]). CONCLUSION: Influenza seems to be a frequently underdiagnosed underlying condition in admissions to the C-ICU. Influenza should be screened for at C-ICU admission during influenza epidemics.

BACKGROUND: Prosthetic valve endocarditis (PVE) is a serious infection associated with high mortality that often requires surgical treatment. METHODS: Study on clinical characteristics and prognosis of a large contemporary prospective cohort of prosthetic valve endocarditis (PVE) that included patients diagnosed between January 2008 and December 2020. Univariate and multivariate analysis of factors associated with in-hospital mortality was performed. RESULTS: The study included 1354 cases of PVE. The median age was 71 years with an interquartile range of 62-77 years and 66.9% of the cases were male. Patients diagnosed during the first year after valve implantation (early onset) were characterized by a higher proportion of cases due to coagulase-negative staphylococci and Candida and more perivalvular complications than patients detected after the first year (late onset). In-hospital mortality of PVE in this series was 32.6%; specifically, it was 35.4% in the period 2008-2013 and 29.9% in 2014-2020 (p = 0.031). Variables associated with in-hospital mortality were: Age-adjusted Charlson comorbidity index (OR: 1.15, 95% CI: 1.08-1.23), intracardiac abscess (OR:1.78, 95% CI:1.30-2.44), acute heart failure related to PVE (OR: 3. 11, 95% CI: 2.31-4.19), acute renal failure (OR: 3.11, 95% CI:1.14-2.09), septic shock (OR: 5.56, 95% CI:3.55-8.71), persistent bacteremia (OR: 1.85, 95% CI: 1.21-2.83) and surgery indicated but not performed (OR: 2.08, 95% CI: 1.49-2.89). In-hospital mortality in patients with surgical indication according to guidelines was 31.3% in operated patients and 51.3% in non-operated patients (p<0.001). In the latter group, there were more cases of advanced age, comorbidity, hospital acquired PVE, PVE due to Staphylococcus aureus, septic shock, and stroke. CONCLUSIONS: Not performing cardiac surgery in patients with PVE and surgical indication, according to guidelines, has a significant negative effect on in-hospital mortality. Strategies to better discriminate patients who can benefit most from surgery would be desirable.

Introducción: La implicación de los médicos asistenciales en tareas de investigación clínica presenta grandes diferencias entre las diversas instituciones. Material y método: Estudio transversal basado en una encuesta enviada a los miembros del Grupo de Trabajo de Enfermedades Infecciosas (GTei) de la Sociedad Española de Medicina Interna (SEMI) durante el mes de mayo de 2022. Resultados: De 1.789 miembros del GTei, 169 miembros (9,45%) cumplimentaron la encuesta. La percepción de la conveniencia de participación de cada facultativo en una o varias líneas de investigación fue de 8 puntos (P25:7; P75: 9 puntos). La percepción sobre el estímulo para investigar del sistema sanitario o de la dirección del hospital fue de 2 puntos (1-4), respectivamente. El apoyo a la investigación fue valorado con de 5 (2-7) y 6 (3-7) puntos en relación con el jefe de servicio y los compañeros del departamento, respectivamente. Otros factores evaluados fueron la falta de tiempo por no poder reducir la actividad asistencial (9; 7-10 puntos), la priorización de las actividades de ocio durante el tiempo libre disponible (7; 5-8 puntos), la organización de la carga asistencial (6; 3-9 puntos), las dificultades en la coordinación con otros servicios clínicos o centrales (6; 5-7 puntos y 6; 5-8 puntos, respectivamente). Conclusiones: La investigación clínica es muy bien valorada por los internistas dedicados a la patología infecciosa. Las principales necesidades percibidas son un mayor apoyo institucional y de la dirección del hospital, una mejor organización del departamento, la coordinación interdepartamental y disponer de más tiempo para esta actividad.(AU)
Background: The involvement of attending physicians in clinical research activities differs greatly among institutions. Method: Cross-sectional study based on a survey submitted to the members of the Working Group on Infectious Diseases (GTei) of the Spanish Society of Internal Medicine (SEMI) during the month of May 2022. Results: Out of 1,789 members of the GTei, 169 members (9.45%) completed the survey. The perception of the convenience of participation of each physician in one or more lines of research was 8 points (P25:7; P75: 9 points). The perception of encouragement to do research by the health system or hospital management was 2points (1-4), respectively. Support for research was rated at 5 (2-7) and 6 (3-7) points inrelation to the head of service and colleagues in the department, respectively. Other factors evaluated were the lack of time due to not being able to reduce the care activity (9; 7-10 points), prioritization of leisure activities during available free time (7; 5-8 points), organization of the care load (6; 3-9 points), difficulties in coordinating with other clinical or central services (6; 5-7 points and 6; 5-8 points, respectively). Conclusions: Clinical research is highly valued by internists dedicated to infectious diseases. The main perceived needs are greater institutional and hospital managementsupport, better organization of the department, interdepartmental coordination and more time for this activity. (AU)

INTRODUCTION: The evaluation of staging and activity of invasive fungal infection (IFI) is used to adjust the type and duration of antifungal therapy (AT). Typically anatomy-based imaging is used. Positron emission tomography/CT with 18F-fluorodeoxyglucose (18F-FDG PET/CT) not only evaluates more than one body area in one session, but adds functional information to the anatomic data provided by usual imaging techniques and can potentially improve staging of IFI and monitoring of the response to therapy. Our objective is to analyse the impact of the systematic use of 18F-FDG PET/CT in IFI diagnostic and therapeutic management. METHODS AND ANALYSIS: Multicentre prospective cohort study of IFI with performance of systematic 18F-FDG PET/CT at diagnosis and follow-up that will be carried out in 14 Spanish tertiary hospitals. It is planned to include 224 patients with IFI over a 2-year study period. Findings and changes in management before and after 18F-FDG PET/CT will be compared. Additionally, the association of initial quantitative 18F-FDG PET/CT parameters with response to therapy will be evaluated.The primary endpoint is to compare the yield of 18F-FDG PET/CT with standard management without 18F-FDG PET/CT in IFI at initial assessment (staging) and in monitoring the response to treatment.The impact of the results of 18F-FDG PET/CT on the diagnostic-therapeutic management of patients with IFI (added value), as well as the prognostic ability of different quantification parameters of 18F-FDG PET/CT will be secondary endpoints. ETHICS AND DISSEMINATION: The Clinical Research Ethics Committee of Puerta de Hierro-Majadahonda University Hospital approved the protocol of the study at the primary site. We plan to publish the results in high-impact journals. TRIAL REGISTRATION NUMBER: NCT05688592.

OBJECTIVES: Underlying immunodeficiency has been associated with worse clinical presentation and increased mortality in patients with COVID-19. We evaluated the mortality of solid organ transplant (SOT) recipients (SOTR) hospitalized in Spain due to COVID-19. METHODS: Nationwide, retrospective, observational analysis of all adults hospitalized because of COVID-19 in Spain during 2020. Stratification was made according to SOT status. The National Registry of Hospital Discharges was used, using the International Classification of Diseases, 10th revision coding list. RESULTS: Of the 117,694 adults hospitalized during this period, 491 were SOTR: kidney 390 (79.4%), liver 59 (12%), lung 27 (5.5%), and heart 19 (3.9%). Overall, the mortality of SOTR was 13.8%. After adjustment for baseline characteristics, SOTR was not associated with higher mortality risk (odds ratio [OR] = 0.79, 95% confidence interval [CI] 0.60-1.03). However, lung transplantation was an independent factor related to mortality (OR = 3.26, 95% CI 1.33-7.43), while kidney, liver, and heart transplantation were not. Being a lung transplant recipient was the strongest prognostic factor in SOT patients (OR = 5.12, 95% CI 1.88-13.98). CONCLUSION: This nationwide study supports that the COVID-19 mortality rate in SOTR in Spain during 2020 did not differ from the general population, except for lung transplant recipients, who presented worse outcomes. Efforts should be focused on the optimal management of lung transplant recipients with COVID-19.

Introducción: El trasplante de microbiota fecal (TMF) es un tratamiento avalado por evidencia científica amplia y muy efectivo en el manejo de la infección por Clostridioides difficile (CD). El objetivo de este estudio es analizar su efectividad y seguridad en un ámbito de práctica clínica real. Métodos: Estudio observacional retrospectivo, unicéntrico y descriptivo, en el que se recogieron todos los TMF realizados entre mayo de 2016 y diciembre de 2020. Se definió como éxito técnico la administración exitosa del preparado fecal en el tracto gastrointestinal del receptor y éxito clínico la desaparición de la diarrea en las primeras 72 h tras el procedimiento y ausencia de recidiva a las ocho semanas. Resultados: Se realizaron 15 TMF a 13 pacientes. La edad media de los pacientes fue de 73 ± 19,4 años (rango: 40 a 98 años); siendo el 60% mujeres. La indicación del TMF fue la colitis recidivante por CD en el 84,6%. Todos los TMF se realizaron por colonoscopia y de donantes emparentados. Con un primer procedimiento, el TMF fue efectivo en 11 de 13 pacientes (84,61%; IC 95%; 54,55-98,07). El tiempo hasta la resolución de los síntomas fue menos de 48 h en todos los casos. El seguimiento postrasplante fue de 25,66 ± 17,5 meses. No se registraron complicaciones precoces ni tardías significativas en el seguimiento. Conclusión: El TMF es un procedimiento sencillo, eficaz y seguro en la infección por CD, incluso en pacientes de edad muy avanzada o con grandes comorbilidades.(AU)
Introduction: Faecal microbiota transplantation (FMT) is a treatment supported by wide scientific evidence and proved to be very effective in the management of Clostridioides difficile (CD) infection. The objective of this study is to analyze its effectiveness and safety in a real clinical practice setting. Methods: Retrospective, single-center and descriptive observational study in which all FMT performed between May 2016 and December 2020 were included. Technical success was defined as the successful administration of the fecal preparation in the patient's gastrointestinal tract and clinical success the disappearance of diarrhea in the first 72 h after the procedure with no relapse within the following 8 weeks after the therapy was started. Results: 15 FMT were performed in 13 patients. The mean age of the patients was 73 ± 19,4 years (range: 4098 years); being 60% women. The indication for FMT was relapsing colitis due to CD in 84.6%. All FMTs were performed by colonoscopy and from related donors. With a first procedure, the TMF was effective in 11 of 13 patients (84.61%; 95% CI; 54.5598.07). Time until resolution of symptoms was less than 48h in all cases. Post-transplant follow-up was 25.66 ± 17.5 months. No significant short or long-term complications were recorded at follow-up. Conclusion: TMF is a simple, effective and safe procedure in CD infection, even in elderly patients or those with great comorbidities.(AU)

OBJECTIVES: We aimed to analyse the efficacy and safety of oral sequential therapy (OST) in uncomplicated Staphylococcus aureus bacteraemia (SAB). METHODS: Single-centre observational cohort at a tertiary hospital in Spain, including all patients with the first SAB episode from January 2015 to December 2020. We excluded patients with complicated SAB and those who died during the first week. Patients were classified into the OST group (patients who received oral therapy after initial intravenous antibiotic therapy [IVT]), and IVT group (patients who received exclusively IVT). We performed a propensity-score matching to balance baseline differences. The primary composite endpoint was 90-day mortality or microbiological failure. Secondary endpoints included 90-day SAB relapse. RESULTS: Out of 407 SAB first episodes, 230 (56.5%) were included. Of these, 112 (n = 48.7%) received OST and 118 (51.3%) IVT exclusively. Transition to oral therapy was performed after 7 days (interquartile range, 4-11). The primary endpoint occurred in 10.7% (11/112) in OST vs. 30.5% (36/118) in IVT (p < 0.001). SAB relapses occurred in 3.6% (4/112) vs. 1.7% (2/118) (p 0.436). None of the deaths in OST were related to SAB or its complications. After propensity-score matching, the primary endpoint was not more frequent in the OST group (relative risk, 0.42; 95% CI, 0.22-0.79). Ninety-day relapses occurred similarly in both groups (relative risk, 1.35; 95% CI, 0.75-2.39). DISCUSSION: After an initial intravenous antibiotic, patients with uncomplicated SAB can safely be switched to oral antibiotics without apparent adverse outcomes. This strategy could save costs and complications of prolonged hospital stays. Prospective randomized studies are needed.

OBJECTIVE: We aim to describe the safety and efficacy of sotrovimab in severe cases of COVID-19 in immunocompromised hosts. METHODS: We used a retrospective multicenter cohort including immunocompromised hospitalized patients with severe COVID-19 treated with sotrovimab between October 2021 and December 2021. RESULTS: We included 32 patients. The main immunocompromising conditions were solid organ transplantation (46.9%) and hematological malignancy (37.5%). Seven patients (21.9%) had respiratory progression: 12.5% died and 9.4% required mechanical ventilation. Patients treated within the first 14 days of their symptoms had a lower progression rate: 12.0% vs. 57.1%, p = 0.029. No adverse event was attributed to sotrovimab. CONCLUSIONS: Sotrovimab was safe and may be effective in its use for immunocompromised patients with severe COVID-19. More studies are needed to confirm these preliminary data.
ABSTRACT
BACKGROUND AND OBJECTIVES: There is a concern about a possible deleterious effect of pathogen reduction (PR) with methylene blue (MB) on the function of immunoglobulins of COVID-19 convalescent plasma (CCP). We have evaluated whether MB-treated CCP is associated with a poorer clinical response compared to other inactivation systems at the ConPlas-19 clinical trial. MATERIALS AND METHODS: This was an ad hoc sub-study of the ConPlas-19 clinical trial comparing the proportion of patients transfused with MB-treated CCP who had a worsening of respiration versus those treated with amotosalen (AM) or riboflavin (RB). RESULTS: One-hundred and seventy-five inpatients with SARS-CoV-2 pneumonia were transfused with a single CCP unit. The inactivation system of the CCP units transfused was MB in 90 patients (51.4%), RB in 60 (34.3%) and AM in 25 (14.3%). Five out of 90 patients (5.6%) transfused with MB-treated CCP had worsening respiration compared to 9 out of 85 patients (10.6%) treated with alternative PR methods (p = 0.220). Of note, MB showed a trend towards a lower rate of respiratory progressions at 28 days (risk ratio, 0.52; 95% confidence interval, 0.18-1.50). CONCLUSION: Our data suggest that MB-treated CCP does not provide a worse clinical outcome compared to the other PR methods for the treatment of COVID-19.
